uPVC Profiles have good corrosion resistance, so the corrosion resistance of plastic steel doors and windows mainly depends on the choice of hardware, such as the selection of anti-corrosion hardware, stainless steel, and its service life is about 10 times that of steel windows. Now let's take a look at how uPVC Profiles perform anti-corrosion treatment.
Anti-corrosion treatment of uPVC Profiles: In addition to the assembly clearance of various uPVC Profiles to be assembled, it is also very important whether the sealing strip is uniform and firm, and the interface clearance should not be greater than 1mm, which reflects the sealing performance. uPVC Profiles are usually used for building materials, and the sealing requirements are not so high.
Various clearance values are specified in national standards, but for customers, the smaller the clearance value at the joints of various profiles, the tighter the fit and the more exquisite the assembly process, which reflects the level of assembly and the accuracy of assembly tools. uPVC Profiles shall apply anti-corrosion treatment to the contact surface with the cement mortar. Before plastering, the uPVC Profiles should be wrapped or pasted with plastic film for protection. Before the installation of the uPVC Profiles and the indoor and outdoor wet work is not completed, the plastic film should not be damaged. Prevent mortar from eroding its surface.
The protective film of uPVC Profiles should be torn off before delivery. It should be torn off lightly, and a shovel should not be used to prevent scratching the surface and affecting the appearance. If there is gelatinous substance on the surface of uPVC Profiles, it should be wiped clean with cotton silk dipped in special solvent. During the erection and dismantling of shelves, outdoor plastering, steel keel installation, pipeline construction and transportation, it is strictly forbidden to wipe or smash the uPVC Profiles frame. This ensures that our profiles are not corroded.
